2 SHEETS-SHEET 2 THOMAS J'. ELLISON, 0F TERRILL, KENTUCKY.

CORN-PLANTER.

Application filed July 14. 1916.

To all whom it may concern:

Beit known that I, THOMAS J. ELLIsoN, a citizen of the United States, residing at Terrill, in the county of Madison and State of' Kentucky, haveinvented new and useful improvements in Corn-Planters, of which the following is a speclficatlon.

The machine which is the subject matterV of the present application for patent is designed more particularly for planting corn, and the invention has for its object to provide a novel and improved mechanism for correctly dropping the seed atv regular spaced intervals, and toy effect this result drawings, lforming a part of this specifica' tion.

In the drawings, Figure 1 is a plan view of the machine,

i with parts broken away and shown in section;

Fig. 2 is a longitudinal section on the line 2--2 of Fig. 1, and

Fig. 3 is a horizontal section of one of the seed boxes.

Referring specifically to the drawings, 5

denotes the main frame of the machine, the` same being constructed and arranged in any suitable manner. The frame is mounted on a pair of wheels 6 carried by an axle 7 suitably fixed to the frame. At the front of the main frame is a suitable support 8 carrying the seed boxes 9, two ofsuch being provided as is the common practice.

From each seed box 9 depends a seed chute 10 extending down to a furrow opener 11 as usual. In the seed chute is mounted a valve 12 pivoted intermediate its ends, as Shown at 13 and having its upper end located opposite one edge of a horizontal slide bar 14 provided in said edge with a cam recess 15. The last-mentioned end of the valve has an anti-friction roller 16 engaging the cam edge of the slide bar. Vhen the bar 10 is reciprocated, the valve 12 is rocked by the movement of the roller 16 into and out of the recess 15. r1`he valve 12 is backed by a spring 17 which tends to urge its upper end toward the bar 14, so that when the recess 15 Specification of Letters Patent.

' comes opposite the roller 16, the latter enters the recess and the upper end of the valve therefore tilts forward, whereupon its rear end tilts back to open position, and allows the seed resting thereon to drop. In the bar 14 is an opening 18, Awhich latter, whenthe valve is in closed position, registers Vwith the outlet 19 of the seed box 9 into the chute 10, and allows the seed to drop down the chute onto the valve. The bar 14 then moves back to cover Vthe outlet 19, shutting off the iow of seed to the valve, and the latter now opens and allows the seed resting thereon to drop to the ground. The

area of the opening 18 may be varied by a slide 2O carried by the bar 14, thereby regulating the quantity of seeddelivered to the valve at each operation.

It will be understood that the seed dropping mechanism just described is the same in both seed boxes 9, and both are operated by the bar 14, the latter extending throughboth boxes.

The following means are provided for operating the slide bar 14,:

To one of the 'wheels 6 is fixed a toothed clutch ring 21, and opposite the same, is a clutch ring 22 which is fixed to a pair of tappet arms 23 extending radially outward, from a hub 24 slidably mounted on the axle 7. When the hub 24 is slid toward the wheel 6 to bring the clutch rings 21 and 22 into engagement, the arms 23 revolve with the wheel. At the side, thc outer ends of the arms 23 carry rollers 25 into the path of which extends a lateral bend or crank arm 26 on one end of a rock shaft 27 journaled in bearings 28 carried by one of the seed boxes 9. A rocker arm 29 is fixed at one end to the shaft 27 and extends loosely through a slot 30 in the bar 14, and has connected to its lower end a spring 31 tending to draw the arm in one direction, and rock the shaft 27 in a direction to bring the crank arm 26 back into the path of the rollers 25.

ln operation, the arms 23 being in motion, the rollers 25, one after the other, strike the crank arm 26, whereupon the shaft 27 is rocked, and when a roller slips off the crank arm, the shaft 27 is rocked by the spring 31 to swing the crank arm back into the path of the next approaching roller. The motion of shaft 27 is transmitted to the bar 14 through the arm 29, and the bar is reciprocated to operate the seed dropping mechanism hereinbefore: described. The

hub 24 has an opening 32 so that-another vvtappet arm may be added if it is desired to drill ther seed inA hills twenty-one inches apart.

The bearings 2S carrying the rock shaft 27 are vertically adjustable to regulate the stroke of the bar 1st by varying the distance between the rock shaft and the point Where the arm 29 connects with the bar 14.

The machine is also equipped with a Seat tl for the driver, a marker 42 to drive by, (shown partly broken away in Fig. 1), Scrapersy 43 for the'wheels 6, and such other adjuncts as may be required, which need not be described in detail as they iorm no part of the present invention `I claim: I
